Product Overview
MMBFJ177LT1G is a onsemi device in the JFETs category, supplied in a SOT-23 package.
Verified selection data includes Configuration: 1 P-channel, Gate-Source Cutoff Voltage (VGS(off)): 800mV, Gate-Source Breakdown Voltage (VGSS): 30V, Power Dissipation (PD): 225mW.
The broad I_{DSS} range and specified V_{GS(off)} require bias and switch-resistance analysis across production spread. The low-pF capacitances support low-level switching but still require charge-injection and bandwidth checks.

Selection Notes
P-channel polarity; I_{DSS} range; cutoff-voltage range; on-resistance; capacitance; standard versus automotive S variant.
Match channel polarity, VGS(off), breakdown voltage, current range and dissipation to the analog switch or bias point.
Manufacturer Decision-Relevant Notes
V_{(BR)GSS} min 30 V; I_{DSS} min 1.5 mA, max 20 mA at V_{GS}=0, V_{DS}=-15 V; I_{D(off)} max 1 nA at V_{DS}=-15 V, V_{GS}=10 V; V_{GS(off)} min 0.8 V, max 2.5 V; r_{DS(on)} max 300 Ω at I_D=-500 µ A; C_{iss} typ 11 pF; C_{rss} typ 5.5 pF at 1 MHz.
Design Considerations
- Verify negative-polarity voltage margins against V_{DG} and V_{GS}; calculate worst-case I_D r_{DS(on)} using 300 Ω; verify gate leakage at the actual temperature and gate bias; confirm SOT-23 thermal dissipation and reflow profile.
Application Fit
Analog switching, sample-and-hold, chopper-stabilized amplifiers.
Exact Variant and Procurement Notes
SOT-23 (TO-236), Pb-free; 3,000 pieces/tape-and-reel. The related SMMBFJ177LT1G is the automotive-qualified variant; do not treat it as the same MPN.
